"The only bridge of interest [over the River Ryburn] is the one at Ripponden, situated about 50 yards below the modern by-pass bridge. The width between parapets is 10 feet [3m], and it was probably built after the flood of 1722 which destroyed seceral bridges in this district." - E. Jervoise, Ancient bridges of the north of England (1931)
